FlutterNativeSplash.preserve not working on flutter 3.16

[anokabb]

After upgrading to flutter 3.16 and also using the latest flutter native splash version after the splash displayed it's disappears and shows a black screen until you call FlutterNativeSplash.remove();

Configuration

flutter_native_splash:
color: "#000f55"
image: images/splash.png

• Device: Pixel 7 Pro
• OS: Android 12

To Reproduce
Steps to reproduce the behavior:

1. Setup FlutterNativeSplash.preserve(widgetsBinding: widgetsBinding) on main
2. Remove or comment FlutterNativeSplash.remove();
3. then you will be stuck on black screen

@jonbhanson still getting this issue, i'm using latest versions flutter_native_splash: ^2.3.10 and flutter:3.16.9

[jonbhanson]

@anokabb I was not able to reproduce this. Can you supply a minimal project that demonstrates this error?

I'm experiencing the same issue after upgrading flutter from 3.10.7 to 3.19.6

@jonbhanson, doesn't work for me either.

I do call FlutterNativeSplash.preserve(); and intentionally don't call FlutterNativeSplash.remove();, but still see that LaunchBackground (or LaunchScreen.storyboard?) fades out into black.

For now, I don't even know what to check for possible solutions

Target: iOS only
Flutter: 3.24.0
Package: 2.4.1

EDIT: 6 hours spent figuring out the issue, and after adding this comment I've nailed it. Magic.
So, the issue was in selection LaunchScreen.storyboard from XCode UI (I specidied it in Runner -> Runner (under Targets) -> General tab -> App Icons and Launch Screens -> Launch Screen File). This change updated my Info.plist files with the following changes:

<key>UILaunchStoryboardName</key>
<string>LaunchScreen.storyboard</string>

Removing the extension .storyboard fixed the issue:

<key>UILaunchStoryboardName</key>
<string>LaunchScreen</string>

I hope this will help @UmidjonOkhunov
@jonbhanson, you can re-check this behavior and add a notice to the readme.

EDIT 2: Well, now I see the difference. For some reason, now the launch screen starts fading in from the black color the the background image. I don't know why adding/removing extension changes this behavior
